Android12 Launcher3显示所有应用列表
1.前言：
最近在Android12Rom定制时需要显示所有桌面应用的图标，并且不能去掉抽屉，在手机上面抽屉和所有应该列表是两种不同模式，用户基可以自行选择，但是在自定义的launcher中这些和原生Rom一起定制时会出现，特别在Android12及以上的版本，这里就讲解一下不去掉抽屉的方式在桌面显示所有应用App图标.
1.修改config.xml
源码路径：packages/apps/launcher3/res/value/config.xml
添加以下代码：
<string name="app_filter_class" translatable="false"></string>
2.修改AppFilter：
源码路径：packages/apps/launcher3/src/com/android/launcher3/AppFilter.java
public class AppFilter implements ResourceBasedOverride {
private final Set<ComponentName> mFilteredComponents;
.collect(Collectors.toSet());
}
public static AppFilter newInstance(Context context) {
return Overrides.getObject(AppFilter.class, context, R.string.app_filter_class);
}
public boolean shouldShowApp(ComponentName app) {
//显示所有App
// return !mFilteredComponents.contains(app);
//add start
return true;
//add end
}
}
3.修改SessionCommitReceiver：
源码路径：packages/apps/launcher3/src/com/android/launcher3/SessionCommitReceiver.java
核心修改如下：
if (TextUtils.isEmpty(info.getAppPackageName())
//add start
// || info.getInstallReason() != PackageManager.INSTALL_REASON_USER
//add end
|| packageInstallerCompat.promiseIconAddedForId(info.getSessionId())) {
packageInstallerCompat.removePromiseIconId(info.getSessionId());
return;
}
package com.android.launcher3;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageInstaller;
import android.content.pm.PackageInstaller.SessionInfo;
import android.content.pm.PackageManager;
import android.os.UserHandle;
import android.text.TextUtils;
import androidx.annotation.WorkerThread;
import com.android.launcher3.logging.FileLog;
import com.android.launcher3.model.ItemInstallQueue;
import com.android.launcher3.pm.InstallSessionHelper;
import com.android.launcher3.util.Executors;
/**
* BroadcastReceiver to handle session commit intent.
*/
public class SessionCommitReceiver extends BroadcastReceiver {
private static final String LOG = "SessionCommitReceiver";
// Preference key for automatically adding icon to homescreen.
public static final String ADD_ICON_PREFERENCE_KEY = "pref_add_icon_to_home";
@Override
public void onReceive(Context context, Intent intent) {
Executors.MODEL_EXECUTOR.execute(() -> processIntent(context, intent));
}
@WorkerThread
private static void processIntent(Context context, Intent intent) {
if (!isEnabled(context)) {
// User has decided to not add icons on homescreen.
return;
}
SessionInfo info = intent.getParcelableExtra(PackageInstaller.EXTRA_SESSION);
UserHandle user = intent.getParcelableExtra(Intent.EXTRA_USER);
if (!PackageInstaller.ACTION_SESSION_COMMITTED.equals(intent.getAction())
|| info == null || user == null) {
// Invalid intent.
return;
}
InstallSessionHelper packageInstallerCompat = InstallSessionHelper.INSTANCE.get(context);
packageInstallerCompat.restoreDbIfApplicable(info);
if (TextUtils.isEmpty(info.getAppPackageName())
//add start
// || info.getInstallReason() != PackageManager.INSTALL_REASON_USER
//add end
|| packageInstallerCompat.promiseIconAddedForId(info.getSessionId())) {
packageInstallerCompat.removePromiseIconId(info.getSessionId());
return;
}
FileLog.d(LOG,
"Adding package name to install queue. Package name: " + info.getAppPackageName()
+ ", has app icon: " + (info.getAppIcon() != null)
+ ", has app label: " + !TextUtils.isEmpty(info.getAppLabel()));
ItemInstallQueue.INSTANCE.get(context)
.queueItem(info.getAppPackageName(), user);
}
public static boolean isEnabled(Context context) {
return Utilities.getPrefs(context).getBoolean(ADD_ICON_PREFERENCE_KEY, true);
}
}
4.修改FeatureFlags:
源码路径：packages/apps/launcher3/src/com/android/launcher3/config/FeatureFlags.java
核心修改如下：
/**
* true: All applications are displayed in the workspace. Turn off the display of the allapp list
*/
public static final boolean REMOVE_DRAWER = true;
5.修改AddWorkspaceItemsTask:
源码路径：packages/apps/launcher3/src/com/android/launcher3/model/AddWorkspaceItemsTask.java
核心修改如下：
package com.android.launcher3.model;
// add start
/* if(!FeatureFlags.REMOVE_DRAWER){
if (PackageManagerHelper.isSystemApp(app.getContext(), item.getIntent())) {
continue;
}
} */
// add end
// add start
if (FeatureFlags.REMOVE_DRAWER) {
preferredScreenIndex = 0;
}
// add end
6.修改BaseModelUpdateTask:
源码路径：packages/apps/launcher3/src/com/android/launcher3/model/BaseModelUpdateTask.java
核心修改如下：
package com.android.launcher3.model;
//add start
/* if(!FeatureFlags.REMOVE_DRAWER){
return;
} */
//add end
}
7.修改LoaderTask:
源码路径：packages/apps/launcher3/src/com/android/launcher3/model/LoaderTask.java

9.实现效果如下：
10.总结:
由于字符限制有些完整源码去掉了，大家可以参考我的csdn博客，从上面的截图可以看到基本上实现了桌面显示所有App应用图标，不同于抽屉模式还要向上滑动才能看到整个应用列表，这也很符合用户使用真实手机的习惯，而且安装了新App后会再桌面刷新，后面会讲解去掉抽屉显示所有应用列表.

- 几处关键修改就是显示所有应用，在桌面加载和安装新应用后立即刷新
- shouldShowApp显示所有App不过滤
- 在LoaderTask添加bindAllAppsToWorkspace()方法
- 在PackageUpdatedTask添加updateAllAppsToWorkspace()方法
